【摘要】 针对变速恒频双馈异步风力发电机的风电系统,以仿真软件EMTP RV为平台,搭建风电场的模型,充分考虑风电场在不同风况、有无系统背景谐波以及考虑系统三相不平衡电压等情况下,仿真分析风电机组并网的公共连接点处谐波电压情况,根据仿真结果,提出有指导意义的建议和对策,具有现实的参考价值。更多还原

【Abstract】 As to variable speed constant frequency doubly-fed induction generators(DFIG),the wind farm modeling in the simulation software EMTP_RV was built,and the harmonic voltage of the wind generator in interconnection of common connection point,in varies of the wind farms,such as different wind speed,whether in different background harmonic was simulated and analyzed,and consider system voltage unbalanced three-phase was considered.According to the simulation results,some suggestions and countermeasures of guidance were put forward,those have realistic reference value.更多还原
